CREAM-SEIPAEATOR LINER.

Specification of Letters Patent.

Patented Jan. 11, 191%.

Application filed September 2 1, 1908. Serial No. 454,500.

To all whom it may concern:

Be it known that I, EDGERLY It. BAILEY, a citizen of the United States,residing at Clarinda, in the county of Page and State of Iowa, haveinvented certain new and useful Improvements in Cream-Separator Liners;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to separators, and particularly to centrifugalcream separators.

The object of the invention is the provision of a device of thischaracter which will prevent any lagging in the strata of milk as itpasses from the feed opening to the exit, thus obtaining a uniformseparation and a higher cream percentage.

\Vith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a central vertical section;Fig. 2 is a horizontal section taken on the line 22 of Fig. 1, and Fig.3 is a sectional view taken on the line 8-? of Fig. 1.

Referring more especially to the drawings, 1 represents the shaft of aseparator which is driven in any suitable manner, and is preferablyconnected integral with the bowl 2, as shown. Inside of the bowl thecasting is made sufliciently heavy to include a neck or projection 3,which is hollowed out at 4,-

and threaded at 5, to receive the inlet tube 6. The socket 1- isapertured at 7 to permit the passage of the milk to the bowl. At theupper end of the bowl I provide a suitable cover or cap 8, which is heldin position upon the bowl by a retaining ring 9, held against the cap ofa set screw 10, threaded on to the upper or inlet end 11 of the tube 6.Inside of the bowl and surrounding the neck 3 is a perforatedcone-shaped disk 12, having an outer and inner row of perforations 13and 14, the former being adapted to permit the passage of milk, and thelatter being arranged higher up adjacent the center of the disk for thepassage of the cream. Extending vertically from the cone 12 and rigidlysecured thereto are a plurality of tangentially extending vanes 15, oneof which 16 v is somewhat wider than the others for a purpose which willbe hereinafter described. These vanes are all riveted or otherwisesecured to the cone 12 and extend up with their inner edges parallelwith the tube 6, and with their tangential direction of extensionintersecting the radial lines at approximately the vertical center oftheir bodies. The upper ends of these vanes are securely riveted to adisk 17, which is apertured at 18, to permit the passage of the tube 6.This disk tightly engages the tube 6, and is cut away intermediate thevanes 15 as at 19 to permit the passage of the cream. In thisconstruction of separator, I secure between the cap and the upper edgeof the bowl the usual skimming ring 20, which is provided with theoutlettubes 21, of any suitable number. The cream outlet opening is notshown herein, but may be located at any point which is deemed advisable.

Secured to the vanes 15 are the usual liner plates 22, which are slottedat 23, to receive the vanes when they are slipped into place. Each linerplate is also provided with a slot 24-, to receive the vane 16, and inthis manner the vanes and liner plates are held securely within thebowl. In assembling the device, the liner plates being provided with theslot 2 L can only be fitted in the correct manner, the wide vane actingas a guide to prevent incorrect assembling. Each liner plate is providedwith a plurality of punched up knobs, 25, which hold the same inseparated position, as will be clearly seen from an inspection of Fig.1.

While the cone 12 is tightly secured upon the neck 3, I preferablyengage the same with a stud 26, which is carried by the bottom of thebowl and positively prevents the cone 12 and its connected parts fromturning.

In the operation of the device, milk is fed from the upper end 11 of thetube 6 to the recess 4 and from thence through the openings 7 into thebowl 2 under the cone 12. The milk is then thrown out under the effectof the centrifugal force, the cream immediately escaping through theapertures 14: and the milk through the outlets 13. As the milk rises inthe bowl from constant feeding,

the vanes 15, it will be seen, are arranged so as to intersect theradial lines and to increase the efliciency of the device, acting uponthe milk to overcome the inertia and prevent lagging of the differentstratum between the separate liner plates. The cream rises through thecenter of the bowl adjacent the tube Gand passes around through thecutaway portions 19 to its outlet (not shown).

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention, what I claim and desire to secure byLetters-Patent is 1. In a centrifugal liquid separator, a linercomprising rigidly connected end and intermediate members, and a seriesof loosely mounted nested conical liner plates or rings locatedintermediate said end members and engaged with said connected members.

2. In a centrifugal liquid separator, a liner comprising rigidlyconnected end and intermediate members, a series of loosely mountednested conical liner plates or rings located intermediate said endmembers and movable with the said connected members, and means forpreventing the rotation of said conical plates or rings which at thesame time permits a free longitudinal movement. thereof.

3. A liner for centrifugal liquid separa tors, comprising a series ofobliquely disposed circularly arranged bars, annulus disk members at therespective ends thereof rigidly secured thereto and the same forming aunitary centering cage, and a series of conical superposed nestedannulus plates loosely mounted around and movable lengthwise of saidbars.

4. In a centrifugal separator, the combination with a bowl, of a socketformed in its base, a central feed pipe secured in said socket, a coneseated in said bowl around said socket and having cream and milkapertures, a plurality of liner plates arranged in vertical sequenceabove the cone and surrounding said feed tube, said liner )lates beingprovided with a plurality of di 'erent sized slots, vertically extendingvanes secured to said cone and arranged tangentially to the inlet tube,said vanes secured in the slots of the liner plates, a disk tightlyengaging said inlet tube and connected with said vanes to hold the upperend thereof in proper alinement, said disk having a plurality of notchesvertically alined with the cream apertures, a cap for the bowl, andmeans carried by the feed pipe for holding the cap in position on thebowl.

In a centrifugal separator, the combination with a bowl, of a coneresting on the bottom of the bowl and having a plurality of creamopenings, a plurality of vertically arranged vanes supported on the coneand arranged alternately with the cream openings, a notched disk securedto the upper end of said vanes to hold the same in spaced relation, thenotches in the disk being vertically alined with the cream openings, andliner plates surrounding the vanes and secured thereto.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
